Re: oozie cannot access hdfs from machine outside the oozie cluster.
Harshal,
If you are having issues setting up CDH Hadoop/Oozie please use the
cdh-user@ alias. I'm moving the thread there, BCCing oozie-users@ alias.
You don't need to replace KerberosAuthenticatorService, actually you need
that service, even if you are not using Kerberos.
It seems that you network setup a bit too complex.
Would be possible for you to try out first installing everything in a
single machine following the instructions?
Thanks.

RE: oozie cannot access hdfs from machine outside the oozie cluster.

The name is harshal-centos-vir:8020.
I think in the logs it prints both domain name and ip address.

What are your machine names and your namenode configurations in your

The following name looks weird: harshal-centos-vir/10.42.43.11:8020

As i had mentioned in my previous email, everything is working on one machine. The issue is when I install oozie on a separate machine.

Harshal,
If you are having issues setting up CDH Hadoop/Oozie please use the
cdh-user@ alias. I'm moving the thread there, BCCing oozie-users@ alias.
You don't need to replace KerberosAuthenticatorService, actually you need
that service, even if you are not using Kerberos.
It seems that you network setup a bit too complex.
Would be possible for you to try out first installing everything in a
single machine following the instructions?
Thanks.
